AFC has more than 6,000 large systems installed worldwide. Application engineers and system designers use computer aided design techniques to tailor systems to end user needs. Our laboratories work with you to select the best system components and filter media to remove waste solids from fluids.

• Vacuum filtration systems boost metalworking productivity. Tool life doubles, triples or more. Cooling and lubricating fluids can last indefinitely. Uptime climbs because of fewer tool changes and less machine maintenance. Chip disposal is simplified. Critical tolerances and surface finishes improve dramatically.

• Vacuum systems have only three moving parts: the filter/distribution pump, the flight conveyor and the vacuum break valve. This keeps maintenance low and system reliability high.
• Energy costs are low because the same pump generates filter vacuum and delivers pressurized liquid to production machines.

Vacuum systems filter mineral oils, soluble oils, semi synthetic and other fluids at flow rates of up to 50,000 L/min. Self-contained centralized units can be installed above or below floor, or in mobile configurations to handle single machines, machine centers, deparments or entire plants. Add optional, automatic chip processing and waste disposal for complete system efficiency.

Media Options

• Filter media is designed for specific applications ranging from rough machining to grinding, honing and polishing.

• Larger fines can be retained by permanent filter media such as stainless steel wedge wire and woven continuous belt media.

• Both are permanent-type media that reduce operating costs. Particulates down to a 10 micron level are removed by low cost, disposable, non-woven media.

Dual filtration for continuous operation.

• AFC Vacuum systems use a unique dual technique to filter and recirculate process liquids. As dirty liquid enters the filter, floating debris and tramp oil is flushed to the discharge ramp and automatically skimmed off the surface by the filter conveyor flights. Simultaneously, liquid is drawn through the filter medium at the bottom of the dirty reservoir by a filter/distribution pump.
• From the clean liquid vacuum chamber, the fluid is continuously pumped to the machines.

•  Automatic operation is ensure by a pre-programmed filter cycle. Initiated automatically when a preselected vacuum is eliminated by backflow of clean liquid lifts the media to prevent migration during indexing. During the index cycle, clean liquid is drawn from a buffer tank to ensure a continuous supply to machines.
• AFC Vacuum systems build up a concentrated solids cake which enhances filtration. The micro indexing feature permits retention of a concentrated solids cake on 90% of the filer area at all times. The filter's ability to develop greater vacuum differential as the solids cake increases maintains uniform flow through the media.
